“ Disporella anhaltina ( Stoliczka, 1862) ” nomen dubium

( Fig. 1K, L )

Pavotubigera anhaltina Stoliczka, 1862: 82 , pl. 1, fig. 8.

MATERIAL EXAMINED. — Holotype of Pavotubigera anhaltina , registered as 1862/0022/0052.

DIAGNOSIS. — Small fragments of discoidal colony with autozooecia in radial fascicles. Fascicles comprising 1-2 parallel rows of apertures, slightly curving from centre of colony. Gonozooecium lacking.

REMARKS

Ŋe specimen is more or less unrecognizable owing to poor preservation and the absence of a gonozooecium. Ŋe arrangement of fascicles,however, resembles some species of Disporella (see Disporella radiata in Zágoršek [2003] and Disporella hispida in Zágoršek [2010]).
